Page 7 of 17

During a pneumatic pressure test a leak test shall be performed in accordance with ASME SEC V Article 10 and Article 10 Appendix I except the pressure shall be 5 10 psi instead of the design pressure. A calculation sheet indicating adequacy of the test Relief Valve shall be included in the procedure.

5.6.2 A request for NDT in lieu of pressure testing shall be submitted for approval as permitted in the specific SAES listed in Section 6 below. A sample form is provided in Appendix I. This form or an equivalent shall be processed prior to NDT.

Commentary Note:

The plant manager will sign the form for existing facilities and the Inspection Department Manager will sign for new construction projects.

5.7 The requirement for pre start-up leak tests and service tests during initial start-up and T&Is shall be as follows:

5.7.1 New systems after strength tests and prior to initial start-up:

5.7.1.1 For systems with maximum operating pressures greater than 6.894 MPa (1000 psi), a leak test with inert gas, followed by a service test, shall be conducted at the maximum operating pressure of the piping system. Oil flowlines, trunklines, testlines and water injection lines are excluded from this requirement.

5.7.1.2 For systems with maximum operating pressures less than 6.894 MPa (1000 psi), a pre start-up leak test with inert gas or steam (if designed for steam service) shall be conducted at the available inert gas or steam system pressure (not exceeding the maximum operating pressure), or pressure as recommended by responsible Operation Engineering Unit, followed by a service test at normal operating pressure of the piping systems. When inert gas or steam are not available, the service test will satisfy the pre start-up leak test requirements.

5.7.2 Existing systems after T&Is:

5.7.2.1 For systems with maximum operating pressures greater than 6.894 MPa (1000 psi) which are in hydrogen service or in sour service with hydrogen sulfide concentrations higher than 0.1 mole %:


Page 8 of 17

5.7.2.1.1 A pre start-up leak test with inert gas shall be conducted after major T&Is. The test pressure shall be determined by the plant Operating Department. For minor T&Is, the pre start-up leak test shall be conducted per 5.7.2.2.

5.7.2.1.2 The pre start-up leak test shall be followed by a service test at the normal operating pressure of the piping.

Commentary Note:

A major T&I is defined as either a catalyst change or a major disassembly of flanges, gaskets, etc. The local Operation Engineering Unit and Inspection Unit have the responsibility to define when a T&I is considered as major. This definition must be made during the pre-T&I scope of work to allow Operations sufficient time to have inert gas on-site prior to start-up of the facility.

5.7.2.2 For all other systems and pressures, a pre start-up leak test with inert gas or steam (if designed for steam service) shall be conducted at the available inert gas or steam system pressure (not exceeding the maximum operating pressure), or at pressure as recommended by responsible Operation Engineering Unit, followed by a service test at normal operating pressure of the piping systems. When inert gas or steam are not available, the service test will satisfy the pre start-up leak test requirements.

5.7.2.3 Procedures for both pre start-up leak tests and service tests shall address, to the extent possible, the safety precautions provided in GI-0002.102 "Pressure Testing Safely".

5.8 If the drop in ambient temperature may cause the test medium to freeze during the test, appropriate precautionary measures must be taken to protect the equipment or piping systems.
